Abstract

This invention relates to antimicrobial lenses containing coated zeolites and methods for their production.

Claims

exact text as granted — not AI-modified
1 . An antimicrobial lens comprising a zeolite coated with at least one hydrophobic substance that slows the release of the antimicrobial metal from the zeolite.  
   
   
       2 . The antimicrobial lens of  claim 1 , wherein the zeolite is coated with a composition comprising at least one silane.  
   
   
       3 . The lens of  claim 1  wherein the zeolite comprises silver.  
   
   
       4 . The lens of  claim 1  wherein the lens is a contact lens.  
   
   
       5 - 17 . (canceled)  
   
   
       18 . The lens of  claim 1  having 
 more than about 0.02 weight percent zeolite, and    less about 1.0 weight percent zeolite.    
   
   
       19 . The lens of  claim 1  having 
 more than about 0.025 weight percent zeolite, and    less about 0.1 weight percent zeolite.    
   
   
       20 . The lens of  claim 1  having 
 more than about zero weight percent zeolite, and    less than about 0.1 weight percent zeolite.    
   
   
       21 .- 22 . (canceled)  
   
   
       23 . The lens of  claim 2  wherein the coated zeolites comprise at least two different hydrophobic substance.  
   
   
       24 . (canceled)  
   
   
       25 . (canceled)  
   
   
       26 . The antimicrobial lens of  claim 1  wherein the hydrophobic compound comprises at least one hydrophobic monomer.  
   
   
       27 . The lens of  claim 26  wherein the hydrophobic monomer is selected from the group consisting of-perfluoropropylene oxide, diethylene glycol vinyl ether, methyl methacrylate, lauryl methacrylate, styrene, 1,3-butadiene, propylene glycol, hexamethylcyclotrisiloxane, and mixtures thereof.  
   
   
       28 . The lens of  claim 26  wherein the hydrophobic monomer is selected from the group consisting of perfluoropropylene oxide, diethylene glycol vinyl ether and mixtures thereof.  
   
   
       29 . The lens of  claim 26  having 
 more than about 0.02 weight percent zeolite, and    less about 1.0 weight percent zeolite.    
   
   
       30 . The lens of  claim 26  having 
 more than about 0.025 weight percent zeolite, and    less about 0.1 weight percent zeolite.    
   
   
       31 . The lens of  claim 26  having 
 more than about zero weight percent zeolite, and    less than about 0.1 weight percent zeolite.    
   
   
       32 .- 52 . (canceled)
